Low-cost fuel cell has higher energy density and produces chemical by-product that could absorb CO2 from the atmosphere ...

Scientists have developed a fuel cell system which they say could ultimately have enough energy capacity to power regional ...

Batteries are nearing their limits in terms of how much power they can store for a given weight. That's a serious obstacle ...

Sodium–air fuel cells could unlock electric flight and clean transit, capturing CO₂ and outperforming lithium batteries.

Many metals react with oxygen to form metal oxides. Potassium and sodium are soft metal which are easily cut exposing a shiny surface which changes to dull rapidly. The change from shiny to dull ...

Hydrogen fuel cells, which power some electric cars, pack far more energy per weight than lithium-ion batteries. The devices ...

A new lightweight sodium metal fuel cell could enable practical electric flight by surpassing the limits of lithium-ion ...

Researchers at the Massachusetts Institute of Technology (MIT) have published a study detailing the performance attributes of ...

A new fuel cell could enable electric airplanes that produce zero carbon emissions, according to a study. Scientists say the ...

Liquid sodium metal fills the tube on one side, and air flows through the other, providing the oxygen for the electrochemical reaction at the center, which ends up gradually consuming the sodium fuel.

Researchers at MIT have developed a low cost fuel cell that, in tests, has proved able to carry there times as much energy as ...
